Other Connections
This section describes the procedures in preparing the external devices that you can connect to
the camera. The camera supports Digital Input and Output (DI/DO) and Audio Input and Output
devices using the bundled terminal blocks. The use of these devices, however, is optional.
How to Connect the DI/DO Devices (Optional)
Depending on your surveillance needs, you may connect digital input or output devices to your
camera to trigger events or notifications.
Digital Input (DI) devices can be used to notify the camera about an activity in the camera site. DI
can be triggers of events. For example, you can connect a “panic button” to the camera; as such
when the panic button is pressed, the alarm signal will be sent through the camera. Other
common DI device applications are emergency button, smoke detector, passive infrared sensor,
etc.
Digital Output (DO) devices are external devices that are activated by the camera upon an event
inside the camera. For example, you can connect an “alarm horn” to the camera; as such when
an event occurs inside the camera (e.g. detected intruder), the alarm horn will sound. Other
common DO device applications are motion-triggered lights, electric fence, magnetic door locks,
etc.
You can connect up to two DI and two DO devices to your camera.
